A machine used to shread cardboard boxes for composting has a first cost of $10,000, an AOC of $7000 per year, a 3-year life, and no appreciable salvage value. Assume you were told that the service provided by the machine will be needed for only 5 years, which entails a repurchase and retention for only 2 years.What salvage value, S, is required after 2 years in order to make the 2-year AW value the same as it is for its 3-year life cycle AW? Assume i = 10% per year. Solve using factors and, if assigned, using a spreadsheet and Goal Seek.

Las Cruces' Virgin Galactic is considering two materials for certain parts in a reusable space vehicle: carbon fiber reinforced plastic (CFRP) and fiber reinforced ceramic (FRC). The costs are shown below. Which should be selected on the basis of a present worth comparison if MARR = 10% per year? (a) Solve using tabulated factors. (b) (Spreadsheet exercises) Solve using single-cell functions. (c) Using your spreadsheet functions, will the selection change if the estimated life of the CFRP material is 4, rather than 2, years? Material CFRP First cost, $ Maintenance cost, $/year -29,000 Salvage value, $ 2,000 Life, years FRC -205,000 -235,000 -27,000 20,000 2 4

A large textile company is trying to decide which sludge dewatering process it should use ahead of its sludge drying operation. The costs associated with centrifuge and belt press systems are shown. Compare them on the basis of their annual worths using an interest rate of 10% per year.   System Centrifuge Belt Press First cost, $ −235,000 −150,000 AOC, $/year −48,000 −41,000 Overhaul in year 2, $ -- −26,000 Salvage value, $ 40,000 10,000 Life, years 6 4   The annual worth of the centrifuge system is $−  , and the annual worth of the belt press system is $−  .   The system selected on the basis of the annual worth analysis is the         (Click to select) belt press centrifuge  system.

An independent contractor for a transportation company needs to determine whether she should upgrade the vehicle she currently owns or trade her vehicle in to lease a new vehicle. If she keeps her vehicle, she will need to invest in immediate upgrades that cost $4,700 and it will cost $1,450 per year to operate at the end of year that follows. She will keep the vehicle for 6 years; at the end of thi period, the upgraded vehicle will have a salvage value of $4,300. Alternatively, she could trade in her vehicle to lease a new vehicle. Sh estimates that her current vehicle has a trade-in value of $9.300 and that there will be $4,500 due at lease signing. She further estimates that it will cost $3,300 per year to lease and operate the vehicle. The independent contractor's MARR is 12%.
